This is a high quality spindle with stainless steel 304 casing and the Germany made ball bearing. New upgraded with adopt germany imported bearing: three times useful time than ordinary spindle motor. Speed: 0-18000 R/min. Runout off: less than 0.005mm. Power: 3 KW.ER20(4mm,6mm,8mm,12mm).This VFD can be used for constant torque loads ( such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). It can be used as a motor speed control and a phase converter. Many customer bought this VFD from us to use for: Lathes, Mills, Car Hoists, Pumps & Conveyors, etc and then performance excellently.
- 【PRODUCT DETAILS】- The 3.0KW air cooled spindle motor's speed is 0-18000 R/min, 300 Hz frequency and less than 0.005 mm runout off. The 4HP 3KW variable frequency drive uses PID control, advanced calculous PID closed-loop arithmetic, quick responding speed and high suitability.
- 【PREMIUM QUALITY】- The spindle motor adopts Germany imported bearing. The VFD is also made of high quality material. So both of them have stable performance, easy operation, high quality, less noise and so on.
- 【POWERFUL PERFORMANCE 】- The variable frequency drive inverter has quick responding speed and high suitability because that it adopts advanced calculous PID closed-loop arithmetic. Apart from this, it has low output ratting torque0.5HZ-150% and low speed running ability.
- 【GREAT PROTECTION SYSTEM】- The perfect error protection and short circuit starting protection are applied in variable frequency drive inverter, which reduces the damage to the machine and extendeds the service life of the product. It will offer you an excellent safety performance.
- 【WORKS COOPERATIVELY】- The air cooled spindle, together with variable frequency drive inverter, it's definitely a nice combination to imporve the work efficiency and performace of the VFD.
